Aid groups evacuating much of their staff from western Africa and our Dr. Richard Besser is tracking it all. You used to work at the CDC. They issued an alert for American doctors. That's right. They have issued an alert to all doctors in America saying be on the watch for anyone who is traveling to this region who could present with fever and this is really, really important.
